High Voltage Power

Our rental high voltage PSUs provide highly stable outputs up to 20kVdc. Precision units are available with adjustable current into the picoamp range.

Programmable voltage ramps are possible, which allow specific output profiles to be achieved. Both positive and negative polarity models are available, as well as units with user switchable polarity. PSUs with dual output channels that are independently controllable also feature within the range.

For critical applications where low noise and high stability are paramount, then the HTP-NHQ is the best option. The unit features a current range resolution of 100pA via a CAN interface.

Due to their exceptional technical features, high voltage PSUs from ETPS are commonly used in high energy physics and nuclear test environments. Specific applications include powering silicon photomultipliers and mass spectrometers, as well as generating X-rays and plasma.

All of our high voltage power supplies are built with advanced resonance mode technology. This makes them among the lightest, smallest and most efficient units on the market. Various case styles are available including 6U cassettes, desktop units and compact modules.

Did you know...


High Precision Dual Channel NIM Cassette


This HTP-NHQ cassette is from the high precision range and features two user adjustable outputs up to 6kV. It has an improved low current range enabling a resolution of 1nA via the display and 100pA via a CAN interface. Output polarity is switchable and the voltage ramp time can be adjusted via a computer interface after switch on.

A recessed 10 position limit switch is provided for both voltage and current. This can be set to help protect sensitive loads against accidental user error. The unit is often found in sensing and detection systems, where low noise and high stability are paramount. Typical industries the HTP-NHQ is used in include medical, nuclear and particle physics.
